As sustainability becomes a greater area of focus throughout the disposable hygiene industry, bringing these adhesives to market now allows Bostik to further support the corporate social responsibility (CSR) efforts of producers for baby care, feminine hygiene, and adult incontinence products. Nuplaviva construction adhesives, initially with 50% and 75% bio-sourced content respectively, provide the same performance and ease of processability expected from Bostik’s traditional adhesive formulations.
“During the research and development stages of Nuplaviva, it was important we designed an end-product that, although bio-based, article manufacturers did not need to make any changes to their equipment or processes to use,” explains Christophe Morel-Fourrier, Bostik’s global marketing manager, market insights and sustainable innovation. “Exacting the formulas to meet the demands of high line speeds added another layer of complexity. But our researchers were successful in meeting expectations for behaviour and performance with both Nuplaviva 50 and Nuplaviva 75.’’
Compatibility with respect to substrate usage in various nappy, pad, and pull-on pant designs was top of mind for Bostik’s scientists as they explored and experimented with the Nuplaviva formulations. Not only do these adhesives work well with traditional substates, but testing has also proven they complement the use of a variety of more sustainable substrates, says Bostik.
